600,000 entries from Lithuania's population register were affected by a data breach.

Omissions

• The breach affected multiple national registers managed by the State Enterprise Centre of Registers, not exclusively the population register (Melderegister). The population register was among the registers impacted, but the scope was broader.
• The breach was discovered in April 2026 and involved unauthorized access by a foreign actor who exploited login credentials assigned to authorised institutions.
• All sources found were published in late May 2026, close to the session date of 17 June 2026, and the MEP could plausibly have known about the breach.
• No primary official source from the Lithuanian government or the Centre of Registers was directly cited; all corroboration comes from independent secondary news outlets.
